AS16276 is OVHcloud's primary ASN — Europe's largest cloud and hosting provider. OVH is known for offering dedicated servers, VPS, and cloud services at aggressive prices. The company operates its own data centres across Europe, North America, Asia, and Australia. OVH IP ranges are frequently seen in security logs due to their popularity with both legitimate customers and malicious actors who exploit cheap hosting.
Every time you visit a website, your IP address — and therefore your ISP (OVH SAS) — is visible to that site. OVH SAS as your ISP can see all unencrypted traffic passing through their network, including the domains you visit. This is standard practice for all ISPs and is typically used for network management, legal compliance, and in some cases targeted advertising.
If your device is assigned an IP in OVH SAS’s ranges, websites you visit will identify your connection as coming from OVH SAS. To prevent this, a VPN replaces your ISP-assigned IP with the VPN server’s IP, making your traffic appear to come from a different provider entirely.
AS16276 is registered with RIPE — the Regional Internet Registry responsible for IP allocations in Europe, the Middle East, and Central Asia. The ASN is used to announce IP prefixes to the global BGP routing table, allowing other networks to route traffic to OVH SAS’s infrastructure.
OVH SAS peers with major transit providers and internet exchanges to ensure global reachability. BGP peering relationships determine how traffic flows between OVH SAS and the rest of the internet.
